  This probably a dumb question, but why in 83 ASM does the shell not do 
the proper set/res commands and clearing neccessary for running ASM 
programs. For example, practically every program needs res/set 1,(iy+13) 
to avoid altering the TEXT_MEM (text shadow). Also every game needs to 
clear the GRAPH_MEM and TEXT_MEM before exiting back to the shell. Other 
set/res commands like set/res 2,(iy+13) or set/res 6,(iy+9) are also 
important in many games.
    There are ~12 different set/res commands that are run before and 
after a ASM program is run on the 82 so the programmer doesn't have to 
worry about it, so why can't that be done on the 83 as well?
